This wireless battery-powered sensor installs into the core of your door to become nearly invisible.Used with any compatible control panel/receiver (319.5 MHz wireless frequency), such as a GE/Interlogix Panel (NetworX, Simon, etc.) or a Qolsys IQ Panel, the sensor sends intelligent notifications to your panel, like "door left open". Notifications can be custom-named, so you can know exactly what's going on. Name notifications for the sensor at your front door, for example, "front door left open". For each sensor, you can also determine a unique chime type and turn voice prompts On/Off. Additionally, the sensor can be included in automation rules. For example, you could create a rule that adjusts your thermostat when a door is left open.Provides intelligent notifications such as "door left open"Compatible with 319.5 MHz wireless panels, such as GE/Interlogix or Qolsys IQWireless range up to 600 feet from panel"S-Line" encryption protects signalsBuilt-in tamper switch triggers alert if cover is removedBattery-powered, no wiring requiredHow It WorksThe Recessed Door/Window Sensor consists of two components: the sensor and the magnet. The sensor installs into a 3/4-inch hole drilled into the door/window frame (or the door itself if preferred), and the magnet installs on the door/window itself (or the frame if the sensor is installed in the door). When the sensor detects the magnet has moved more than 1 inch, a notification is triggered.Additional Features:Using Alarm.com (requires optional subscription), you can get a text if your door or window is left openTriggers alerts for tamper, tamper restore, alarm, alarm restore, and low batteryAbout S-Line EncryptionQolsys wireless devices that feature S-Line ("Secure Line") technology offer advanced encryption to safeguard your wireless signals against hacking.The technology employs an advanced encryption scheme between the wireless sensor/device and the control panel to ensure that wireless event transmissions are always unique, preventing and eliminating common replay attacks (when an unscrupulous person uses an easy-to-purchase software-defined radio or "listening device" to replay events that were previously sent by wireless devices paired with a security system.) At time of pairing, S-Line technology passes a unique key which enables the encryption algorithm for unique event transmissions, thereby preventing such replay attacks.ContentsRecessed Door/Window SensorRare Earth MagnetBattery (pre-installed)InstructionsNOTE: Requires connection to a compatible control panel/receiver (319.5 MHz wireless frequency), such as a GE/Interlogix Panel (NetworX, Simon, etc.), Qolsys IQ Panel, Leviton 64-Zone Receiver for GE/Interlogix, Elk M1 Wireless Receiver for GE/Interlogix Crystal Transmitters, or other legacy 319.5 MHz system (all sold separately).Technical DetailsManufacturer Part #: QS1134-840UPC: N/AColor: WhiteBattery: 3V CR2 (x1) included; Replace with exact replacement every 5 years.Transmitter Frequency: 319.5 MHzWireless Signal Range: 600 feet (200 m), open air.Code Outputs: tamper, tamper restore, alarm, alarm restore, low battery.
